Drivers side heated mirror a140

Hi all does anyone have any ideas why my drivers side mirror is not heating up, it did initially work now it seems to have just stopped, passenger side works perfect cheers carl.

It's more than likely a broken wire in the mirror loom.
If you have folding mirrors, even more reason to suspect a broken wire, usually at the point where they fold.

Thank you I dont have folding mirrors, but will check the wiring inside.
